The problem is with the VERSION_CODE and VERSION_NAME. I guess they are missing in your project. You can hardcode the version code and version name like this -

versionCode 21
versionName "1.0"

or can make it dynamic like this -

def versionMajor = 1
def versionMinor = 1
def versionBuild = 0
defaultConfig {
  versionCode versionMajor * 1000000 + versionMinor * 10000 + versionBuild * 100
  versionName "${versionMajor}.${versionMinor}.${versionBuild}"
}
